Ah Mr Frost ! Good trip back to Edinburgh, was it ? If it's any consolation....the flight was delayed till 10pm...lol ! Glad you made it home safe mate.
I agree also, the only thing you can do for stage 2 is just that. Plenty of rest, don't panic, try not to be too nervous and just know that everyone doing the tests are only human, and everyone will make mistakes no matter what.
Good luck to you !
